opening a binary file with the right extension

Hello world

I developed a real simple VI which allows me to read the first five bytes of a binary file for signature (ASCII) and check if its signature match with planned extensions. If Yes, another VI is called and that not one 2 button error message appears: If the user selects OK, a new dialog box opens to choose another file. and if the user chooses cancel, the same dialog box opens instead of escape from the VI.

This is because while loop (VI below), but I don't see how I can handle this without him. Until the user has not chosen the right extension, he cannot escape from what is a problem! The real case is to call one another VI, and the first step of the stacked sequence is to display an error of two buttons.

If you have any ideas, I'm a bit new! Thank you!!

The case of false contains only a true constant connected to any State.

  • How to open multiple files with the same extension in one program from the Explorer

    I frequently receive several JPG (or whatever extension) files to my clients.  On Windows XP, I could just highlight the files I want to open, and then click Open.  They would be so open to 1 program cascading.  This made it easy when comparing many images.  If I do the same thing in Windows 7, it opens the default program several times and puts 1 image of each open program.  It is Paint Shop Pro in my case.  Thus, instead of so-called images 5 open cascading in Paint Shop Pro... the computer open Paint Shop Pro 5 times with 1 image of each open version of the program.  I tried this search like crazy, but cannot find the right thread for an answer.  Most of the threads are on the opening of the different file types.  My question is only about the opening of multiple files with the same exact file inside 1 free program extension.

    Is this the same version of Paint Shop?

    One thing you might try is to open Paint Shop, then select and drag all the files in this window of the paint shop.  Various programs to manage this type of action differently from the DDE, but it might give you the expected results.

  • Downloading files with the docx extension fails in the APEX 3.1.0.00.32

    Hello

    In my application, if I try to download files with extension of 4 characters, IE for example .docx, download fails with this error message:

    Not found

    The requested URL /pls/apex/wwv_flow.accept was not found.

    If I download files with extension of 3 characters, everything works fine.

    Is this a bug in APEX? Is that a way out of this error?

    Is this a bug in APEX? Is that a way out of this error?

    Because of limits on the size of the columns of the MIME type, DOCX and other MS Office XML file formats are not supported in APEX 3.1.

    A patch for APEX version 3.2.1.00.12 is available on My Oracle Support under the bug number 9770959.

    The problem is completely resolved in APEX 4.x.

    Support for APEX 3.1 ended in February 2011. You should go to APEX 4.2 for ongoing support and enjoy many new features.

  • Why do my files with the .php extension have no syntax highlighting?

    Syntax coloring works great for .html, .css, .js, etc.. By .php files have nothing. Help please?

    Apparently the problem was me, but not sure how it happened. For this .php file my mode switched over to the design. I does not recognize this, however, because there are line numbers, which I do not know whence they came. I have copied from a file and pasted into another, although I still don't know how the line numbers got there. Once I have switched back to code view, my syntax coloring was there. Who knows, maybe it will help someone with the same irregular deadlines? Thanks for the replies!

  • Download binary files with the RESTful web service = HTTP 500?

    I want to allow access to the photos (BLOBs) stored in the database via a RESTful APEX service.

    I have an API of PL/SQL existing based on wpg_docload.download_file works well when called directly on the URL (for example granted to APEX_PUBLIC_USER). I would like to re - use this API because it a lot of other things, including security and the cache.

    The code looks like:
    ===
    Photo of procedure (id number, v in varchar2) is
    l_blob blob.
    -- ...
    Start
    -security checks
    -extract the data in l_blob...
    -check if the document has been updated (304)
    -- ...
    owa_util.mime_header (l_mime_type, false);
    HTP.p ("Content-length: ' |") DBMS_LOB.GetLength (l_blob));
    HTP.p ("ETag:" | ") l_etag);
    HTP.p ('Cache-Control: public');
    owa_util.http_header_close;
    wpg_docload.download_file (l_blob);
    end;
    ===

    However, when I call this API with APEX 4.2.1 Restful WebService (the GET - PL/SQL source type resource manager) I get a "500 - internal server error" back to the listener of the APEX (2.0.0.354.17.08 - both running standalone or with Tomcat 7) - console log attached.

    A similar approach - APEX RESTful WebService API in PL/SQL call - works fine for the content of the STRING/CLOB. So it must be something to do with the wpg_docload.download_file

    No idea how to work around this bug/feature or a suggestion for an alternative approach will be appreciated.

  • How to open files with the .eml extension in Windows 7 Professional

    How to open e-mails that have been saved in the .eml format in Windows 7?  I can record e-mails on my server that works under XP and when I click to open the saved email it opens the e-mail.  When I try to open them from the workstation that is running windows 7, it doesn't do anything but open my email program no real email.  It worked for awhile, but now it doesn't.  I tried to change the "open with" and choose Windows Live Mail (my e-mail program on the two compters) but same thing opens just the real Windows Live Mail not e-mail.  Help, please

    I found the solution: Set Window Live Mail (WLM) defaults for EML files in Winodws 7:

    Control Panal, programs. Set your Defailts to choose default programs, Windows Live Mail, for this program.  Make sure the EML files is checked.

  • Cannot open files with the EXTENSION of the PPT FILE

    I can't open a file with the following extension using PowerPoint ppt. The message below is what I get-

    The selected file is not a valid Microsoft PowerPoint file. It may be a file created by another program.

    Try by double-clicking the file in Windows Explorer to see if another program opens to it. If PowerPoint opens again when you double-click the file in Windows Explorer, it is possible that the file is not a PowerPoint file, but its extension has been renamed to be that of a PowerPoint file type registered (for example, .ppt, .pptx, .pps, .ppsx, .pptx, .pot or .potx) but the file is not a PowerPoint file.

    To determine which program can open the file, try one of the following:

    • Contact the original author (if known) to know what program you used to create this file. Then rename the file with the correct extension so that it can be opened by this program.
    • Try opening the file in other programs.
    • If you or someone you know, are very knowledgeable about software, review the file header in a text editor to determine which program can read the file.

    Another possibility is that the file has been damaged during transfer from another computer. Trying to transfer the file again.

    The file may be damaged. If you have a copy of the file backup, use it. It is not possible repair corrupted file.
